Description
The large-scale magnetic field of the Sun is shaped by the
interplay of active-region emergence, random-walk dispersal
in supergranulation, and advective transport in the
meridional flow and differential rotation. In that process,
active region nests, the plage state, and flow-field
interactions are important to the formation and evolution of
active regions, and likely to the global dynamo process. In
this talk, I plan to review observations and numerical
experiments, looking for an emerging picture, while
identifying some of the open questions.
